Avid readers of historical fiction may already be familiar with the works of Martha Hall Kelly. She brought to life the stories of American philanthropist Caroline Ferriday in “Lilac Girls” and author Georgeanna Woolsey in “Sunflower Sisters.” In the former, the book is mostly set in World War II Europe, but in her upcoming book, “The Martha’s Vineyard Beach and Book Club,” Kelly strikes closer to home as she narrates an intriguing story of how Martha’s Vineyard islanders dealt with the threat of German U-boats, which were getting too close for comfort.
